Abstract :
The millimeter wave filter using two Whispering Gallery mode dielectric disk resonators is presented in this paper. Coupling coefficients of the dual disk resonator and external Q value of the single resonator excited by a dielectric waveguide are investigated theoretically and experimentally. A 2-stage bandpass filter has designed at the center frequency of 69.85GHz with bandwidth of 500MHz. An experimental result is well agreed to theoretical one with low-loss property of 1.8dB insertion loss.
